JOHN W. STANTON, OF NEW YORK, N. Y. ASSIGNORTO THE FIRE EXTIN- GUISHERMANUFACTURING COMPANY, OF SAME PLACE.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 223,402, dated January6, 1880.

Application filed September 22, 1879.

To all whom it may concern.-

Be it known that 1, J OHN W. STANTON, of the city of New York, in thecounty and State it of New York, have invented certain new and usefulImprovements in Fire-Extinguishers,

of which the following is a specification.

My improvements relateto that kind of portable fire-extinguishers inwhich a handpump is employed to throw water or other :0 liquid from aclosed vessel upon a fire. Such vessels are provided with a vent for thefree entrance of air when the pump is in use, so as to admit of the freeand easy working of the pump, and such vent is usually provided with acap or plug for closing the same when the extinguisher is not in use.

My invention consists in the combination, with the vent of afire-extinguisher, of a hosepipe and a nozzle secured to said hosepipeand fitted to said vent, whereby when the extinguisher is not in use thevent is closed by inserting the nozzle therein or applying it thereto.

The invention also consists in a hose-nozzle of novel construction,whereby provision is aiforded for throwing either a stream or a spray.

In the accompanying drawings, Figure 1 represents a side elevation of anextinguisher 3o embodying my improvements, the nozzle being insertedinthe vent-hole. Fig. 2 is a similar view, showing the extinguisher as employed to act upon a fire, the vent-hole being opened; and Fig. 3 is adetail view illustrat- 3 5 ing the manner of using my nozzle.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the vessel or chamber of the fire-extinguisher in which thewater or other 4o liquid is contained, and B apump of ordinaryconstruction for discharging the contents of said vessel or chamber.

C designates apiece of hose eXtendin g from the said pump and serving asa discharge therefor, and D designates a nozzle at the end thereof.

When it is desired to work the extinguisher,

the pump B is operated, and the liquid in the chamber is drawn up andforced out of the discharge-hose C and nozzleD upon the fire.

In order to permit the liquid to be drawn freely from the chamber orvessel, and to prevent the latter from being collapsed, I haverepresented a vent, a, arranged at the top of the vessel A, and thenozzle D corresponds in size and is fitted to the said vent, so as toform a stopper therefor.

In order that the nozzle shall fit tightly in said vent, the holethereof is preferably made tapering or conical, and the tip b of thenoz- 6o zle is correspondingly tapered, and, if desired, a ground jointma be made between the two.

The nozzle might, if desirable, be provided with a mouth-piece fittingoutside the vent in:

stead of inside, as hererepresented.

Many advantages result from forming the nozzle so as to serve as astopper for the venthole, in addition to dispensing with a separate.stopper therefor. When so constructed the ventthimble acts as aprotector or keeper for the nozzle and renders it impossible to use theapparatus without removing the vent-stopper, and therefore there is nosuch liability to collapse the vessel or chamber as there has been in"other extinguishers.

It is also obvious that when the nozzle is inserted in the vent the pumpmay be tried, to ascertain if it is in working order, without removingthe nozzle or spilling and wasting the fire-extin guishin g liquid.

The nozzle D, as represented particularly in Fig. 3, is shown as beveledor slanted at the tip, so as to cut away a portion of the openingthrough it. When the nozzle is. so 0011- 8 structedit may be used forthrowing a solid stream, as represented in Fig. 2; or by placing thethumb or finger upon the beveled end, as clearly illustrated in Fig. 3,the stream of liquid may be scattered and sprayed. The 0 character ofthe stream may be varied at will by slightly moving the position of thethumb. What I claim as my invention, and desire to secure by LettersPatent, is

, 1. The combination, with the vent of a fire- 5 extinguisher, of ahose-pipe and a nozzlese cured tosaid hose-pipe and fiLted to the said3. A hose-nozzle having; one side of its tip Vent, substantially as andfor the purpose beveled orslanted,substantiallyas and for the 10specified. purpose specified.

2. The combination in a fire-extinguisher with a pump and a vent, of adischarge-hose JOHN STANTON for said pump provided with a nozzle whichWitnesses: is fitted to said vent, substantially'as and for HENRY '1.BROWN, the purpose specified. FREDK. HAYNES.
